Hop plant named ‘HBC 522’

Abstract

A new hop plant named ‘HBC 522’ is disclosed. ‘HBC 522’ is used for its exceptional and unique aromatic qualities.

Description

Genus and species: Humulus lupulus.

Variety denomination: ‘HBC 522’.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

None

BACKGROUND OF THE INVENTION

‘HBC 522’ is a product of a controlled breeding program carried out by the inventors in the Yakima Valley of Washington State. ‘HBC 522’ was one of several seedlings resulting from a controlled cross made in 2006 with female parent ‘Columbus’ (U.S. Plant Pat. No. 10,956) and male parent ‘986-2’ (unpatented). A single plant of ‘HBC 522’ was selected in 2009, and in 2010 the plant was asexually reproduced via softwood cuttings in a greenhouse near Toppenish, Wash., and expanded to 30 plants, which were planted in the area of Toppenish, Wash. The plants were observed and evaluated for several years, and in 2014 a 1 acre test plot of ‘HBC 522’ was established in the area of Moxee, Wash. Throughout several generations of asexual propagation, ‘HBC 522’ has been observed to retain its distinctive characteristics and remain true to type.

COMPARISON OF ‘HBC 520’ TO PARENT PLANT AND COMARISON CULTIVAR

‘HBC 522’ is distinguishable from its male parent ‘986-2’ with flowers that develop into mature hop cones without producing pollen, while flowers of ‘986-2’ produce pollen without developing into mature hop cones.

Table 1. below, sets forth some of the distinguishing characteristics of ‘HBC 522’ as compared to its female parent ‘Columbus’, and to the ‘Cascade’ cultivar as a closely comparable cultivar.
